Arizona Court Of Appeals To Hear Challenge To Early Ballot Signature Verification Process

August 7, 2025

The Arizona Court of Appeals is set to hear oral arguments on August 19 in a closely watched lawsuit challenging the state’s early ballot signature verification process—one that could reshape how election officials authenticate mail-in ballots. The case, Arizona Free Enterprise Club v. Fontes, will be heard by Division Two of the Court of Appeals, which lifted a prior stay in the case following a joint request by all parties to move forward on the merits.

At the heart of the dispute is whether the Secretary of State’s Elections Procedures Manual (EPM) has unlawfully expanded the scope of documents used to verify a voter’s signature on early ballot envelopes. The plaintiffs—Arizona Free Enterprise Club, Restoring Integrity and Trust in Elections, and Yavapai County voter Dwight Kadar—argue that Secretary of State Adrian Fontes and his predecessor, now-Governor Katie Hobbs, enforced EPM guidance that violates state law.

Under Arizona statute A.R.S. § 16-550(A), election officials are required to compare a voter’s early ballot envelope signature to the one in their “registration record.” However, the current EPM—originally authored by Hobbs in 2019 and maintained under Fontes—permits election officials to validate signatures by comparing them to any election-related document on file, such as early ballot requests, provisional ballot envelopes, or Active Early Voting List notices.

“The current election procedures manual adopted by the Secretary of State has rewritten state law regarding signature verification for mail-in ballots,” said Arizona Free Enterprise Club President Scot Mussi. “The result is a process that invites questionable methods and opportunities for abuse during the signature review process. It’s time for the courts to bring this illegal EPM practice to a halt.”

The case has had a turbulent procedural history. In 2023, Yavapai County Superior Court Judge John Napper initially ruled that the EPM violated state law, stating that the definition of “registration record” is neither vague nor ambiguous. Napper rejected the Secretary of State’s argument that the term could include any number of election-related documents. However, in a surprising reversal later in the proceedings, Napper ruled in favor of the state—prompting the plaintiffs to appeal.

The outcome of this case could have major consequences for how Arizona handles the verification of early ballots in future elections. Arizona is a state with widespread early and mail-in voting, and signature matching is often the sole method for confirming voter identity on ballots returned by mail. Early ballot voters are not required to provide other identifying information, such as a driver’s license number, date of birth, or the last four digits of a Social Security number.

After months of delays—including a stay prompted by a separate ruling that invalidated the 2023 EPM for procedural reasons—the Court of Appeals has agreed to resume the case. All parties have urged the court to issue a ruling on the merits, regardless of the Arizona Supreme Court’s handling of a related challenge filed by the Republican National Committee.

The court’s decision will help clarify the balance of power between Arizona’s elected officials and its election laws, especially in the increasingly scrutinized area of early voting.
